Doc Text:
A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue as an attacker could have exploited a timing attack by sending a large number of allowCredential entries and detecting the difference between invalid key handles and cross-origin key handles. This could have led to cross-origin account linking in violation of WebAuthn goals.
